to get the subtarget and that's accessible from the MachineFunction now. This helps clear the way for smaller changes where we getting a subtarget will require passing in a MachineFunction/Function as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214988 91177308-0d34-0410-b5e6-96231b3b80d8
